The Early and Mid-Term Follow-up of Drug Eluting Balloon (DEB) For Below the Knee Angioplasty: An Observational Study, MOHAMMED ALI and MAHMOUD NASSER
Abstract
Background: Re-stenosis following infra-popliteal angi-oplasty could results in many serious consequences like recurrence of ischemic symptoms or break through of wound healing. With the evolving techniques of Paclitaxil release and the rapid advancement in the manufacturing of endovas-cular equipment, drug eluting balloons emerge as a useful option to overcome intimal hyperplasia and subsequent re-stenosis.
Aim of Study: To highlight the clinical impact of additional DEB application in patients with CLI attributed to infra-popliteal disease regarding the re-stenosis rate, amputation free survival and limb salvage.
Material and Methods: This study is prospective obser-vational study over a period of one year including 33 patients who underwent infra-popliteal angioplasty using DEB.
Results: 33 patients (36 limbs) were included in the study, 24 cases (27 limbs) were presented by a re-stenosis or occlusion after previous trial of angioplasty using plain balloon, while 9 patients come with the first presentation (Denovo lesions). Stenotic lesions were found in 21 limbs (58.3%) while occlu-sive lesions were observed in 9 limbs (25%) and combined stenotic and occlusive lesions were found in 6 limbs (16.7%). The mean length of the treated lesions within the tibial arteries using DEB was 7.6±3.4m. Primary patency rate at 3, 6 and 12 months was 91.3%, 82.6% and 70.9%. While limb salvage rate at 3, 6 and 12 months was 91.6%, 81.8% and 72.8% respectively.
Conclusion: With the rapid advancement in the endovas-cular tools & equipment, the early results is encouraging and promising with additional application of DEB for patients with infra-popliteal arterial disease in comparison to the traditional use of plain uncoated balloons. However, the mid-term and late results of the IN.PACT DEEP study suggest that an extreme caution is to be considered in this field.
